it seems I am able to run my qt4 applications(like smplayer and qbit torrent) as root but not as a regular user
for qbittorrent:
root:
Qt: Session management error: None of the authentication protocols specified are supported
Couldn't set environment variable...
Peer ID: -qB2970-
HTTP user agent is qBittorrent v2.9.7

What kind of environment are you running these in? How do you start up your X session?_________________"Those who deny freedom to others deserve it not for themselves." - Abraham Lincoln
